Claims (1)

선단의 일측부에 커팅에지(14)가 설치된 인선부(11)의 기단쪽에 목부분(12)이 형성되고, 이 목부분(12)의 기단쪽에 측 형상을 이루는 샹크(13)가 형성되어 이루어지는 보오링바이트에 있어서, 상기한 목부분을, 상기한 샹크축선과 직교하는 방향의 단면시에 있어서의 단면형상이 상기한 샹크(13)의 상기한 단면시에 있어서의 단면의 원호와 동축의 원호를 이루는 축형상으로 형성하여, 이 목부분의 상기한 단면시에 있어서의 단면적을 상기한 샹크(13)의 단면시에 있어서의 단면적을 하회하지 않는 범위에서 그 목부분의 선단에서 기단으로 향함에 따라서 점차 감소시킨 것을 특징으로 하는 보오링 바이트.The neck portion 12 is formed at the proximal end of the cutting edge portion 11 provided with the cutting edge 14 at one side of the tip, and the shank 13 forming a side shape is formed at the proximal end of the neck portion 12. In the boring bite, a cross-sectional shape in the cross section at the cross section of the neck perpendicular to the shank axis is a circular arc and a coaxial arc in the cross section at the cross section of the shank 13 described above. Formed in the form of an axial shape, and the cross-sectional area at the time of the cross section of the neck portion is directed from the tip of the neck portion to the base end within a range not to be less than the cross-sectional area at the cross-section of the shank 13 described above. Therefore, the boring bite characterized in that gradually reduced. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
